Current Loop
The current loop connection scheme is shown in the
. The value
of load resistor should not be higher than 500 Ohms. To reduce noise, it
is recommended to install RC (resistor / capacitor) filter before the
measuring instrument. The filter capacitor value is indicated for
maximum sampling frequency of the sensor (9.4 kHz) and this value
increases in proportion to the frequency reduction.

Voltage Output
The voltage output connection scheme is shown in the. To reduce noise, it
is recommended to install an RC (resistor / capacitor) filter before the
measuring instrument. The filter capacitor value is indicated for
maximum sampling frequency of the sensor (9.4 kHz) and this value
increases in proportion to the frequency reduction.
